Title: Improvements in or relating to automatic pressure-operated valve mechanisms for electric cables
IPC: H02G15/26
Filed: 1947-04-23
Abstract: 630,514. Fluid-actuated valves. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., WOODLAND, C. R., and HOUGHTON, E. I. April 23, 1947, No. 10799. [Class 135] [Also in Group XXXVI] In an electric cable containing nitrogen or other suitable gas under pressure as part of the dielectric material, a diaphragm is acted on differentially by the pressures of the gas in a cable section and in the supply pipe to pivot a lever to open one of two valves permitting a flow of gas to the point of lower pressure. The supply pressure in pipes 11, 12 and bore 22 of a body 10, acts on the lower face of a diaphragm 13 through a passage 21, and the pressure in the cable section acts on the upper face of the diaphragm throughpassage 25. With the supply pressure the greater, the diaphragm moves a lever 17 about its pivot 18, to open a valve 28 permitting gas to flow into the cable, and at the same time, to close electrical contacts 39, 41 providing indication at a control point. With the pressure in the cable section the greater, the lever is moved to open a similar valve 34 permitting gas to flow from the cable to the supply pipe but the electrical contacts are not closed. The valves 28, 34 are urged to their seats by springs 30, 36 respectively, the pressure of which may be varied to enable the valves to be opened at a predetermined pressure differential.

Title: Process for the extraction of lupanine
IPC: A23L11/30
Filed: 1928-04-12
Abstract: 288,637. Ammon, E. von, and Szombathy, K. April 14, 1927, [Convention date]. Lupanine is extracted from seeds of lupins particularly those of lupinus albus by extracting with a solution of a neutral salt sufficiently concentrated to precipitate the conglutin so as to avoid loss thereof. The, solution is treated, e.g. with sulphuric acid, to precipitate the protein dissolved in the salt solution, filtered, and the filtrate rendered alkaline and extracted with benzol from which the lupanine is recovered. Suitable salt solutions for the extraction contain sodium chloride, sodium sulphate, magnesium sulphate, or of calcium chloride. In an example, ground lupin seeds are immersed in water containing calcium chloride. The mixture is allowed to stand and water is added. The ion concentration is increased by the addition of acid, e.g. hydrochloric acid. After several hours the alkaloids are dissolved. The residual seeds containing 25 per cent of liquid and some alkaloid still associated with them are heated with fresh salt solution, after which they are placed in a filter press and finally washed with water at 78‹-82‹ C. The cakes are dried and may be then ground. Sulphuric acid is added to the liquid containing the bulk of the alkaloid to effect the precipitation of the dissolved protein, and the lupanine is extracted with benzol from the solution, filtered and made alkaline, and recovered by crystallization. The lupanine when converted into the hydrochloride can be separated into the d and l forms as the d-lupanine hydrochloric can be dissolved in chloroform while the l-salt remains undissolved.

Title: Improvements in spring-hammers
IPC: B21J7/12
Filed: 1924-05-02
Abstract: 215,742. Kn÷chl, L. May 0, 1923, [Convention date]. Power hammers.- Spring hammers, driven by an eccentric or crank, in which the strength of blow or the stroke of the tup is varied by adjusting the pivot of one member of the operating mechanism, have this adjustment effected by a device which normally holds the pivot stationary but can be adjusted to allow it to move in one or the other direction only, under the reversals of pressure caused by hammering. The pivot may be that of a spring beam 3 or of a rigid beam connected to the tup-slide 2 by a spring, or the pivot 4 of a crank operated lever 8 connected to the hammer beam. The pivot 4 is carried by a frame 12, Fig. 4, having pistons 10, 11 in fixed cylinders 14, 13 which are connected' by a passage 15 in which are arranged oppositely acting non-return valves 16, 17, either of which may be held open by rods 18, 19 and lever 20. In another modification the pivot 4 is carried by lever 21, Fig. 5, having oppositely acting friction ratchets 23, 24 engaging a fixed sector 25 but held slightly apart by an abutment 26 so that during hammering there is some backlash, the ratchets 23, 24 gripping alternately. If the abutment 26 is moved, one of the ratchets is thrown out of action and the device adjusts itself in the desired direction. In another modification the pivot 4 is carried by a rack 27, Fig. 6, in mesh with a pinion 29 secured to a drum 28 which is engaged by two friction ratchets 30, 31 held by a spring 40 against a fixed abutment 39. The ratchets are carried by crank levers 32, 33 either of which can be withdrawn from the drum bv a lever 36 against the action of a spring 34. The Specification as open to inspection under Sect. 91 (3) (a) states also that the pivot 4, Fig. 7 (Cancelled), may be carried by a nut 41 engaged by a screw 42 which can be rotated in either direction by a motor and friction gearing 44. This subject-matter does not appear in the Specification as accepted.

A magnetic chuck is demagnetized by feeding its exciting coil with current which is automatically and repeatedly reversed and reduced in value. In the normal working connection, Fig. 1, the exciting coil W is fed directly from the lines L+, L-, the current flowing through the coil from a to b. In the first demagnetizing step, Fig. 2, the coil is fed through resistances r<SP>1</SP>, r2 connected to its terminals while L - is connected to a, the coil current, which is less than before, then flowing from b to a. In the next step, Fig. 3, the terminal b of the coil is connected to L - through a resistance r3 so that a further reduced current flows from a to b, while in a still further step, which again reduces and reverses the current in the coil, is provided by connecting terminal a to L - through a resistance r4 as shown in Fig. 4. In further steps, which again reverse and reduce the current, resistances r3 and r4 are partly short-circuited in turn. A time delay relay circuit for carrying out these operations is described and resistance values are given.

Title: Improvements in or relating to the manufacture of pyridoxine and its salts
Inventor: HOWSHIP ANTONY STEPHEN
Filed: 1956-04-13
Abstract: In a process for the preparation, concentration or purification of pyridoxin base or salts thereof, a solution of pyridoxine base or pyridoxine salt or salts is contacted with a synthetic ion exchange resin.  A pyridoxine base or salts may be contacted with a synthetic anion exchange resin in the base form to form pyridoxine base which if desired is converted into a pyridoxine salt, or with a strongly basic anion exchange resin to form an anion resin-pyridoxine complex which with a solution of weak easily volatile acid produces a pyridoxine-weak acid salt. Alternatively a pyridoxine salt or salts is contacted with an anion exchange resin in salt form, whereby anion exchange occurs to obtain the desired pyridoxine salt.  A synthetic cation exchange resin in the hydrogen form is contacted with pyridoxine salt or salts to produce a resinpyridoxine base complex which is either contacted with the appropriate acid to obtain the desired salt or contacted with a weak easily volatile base to produce pyridoxine base which may be converted into pyridoxine salt with an acid.  These processes may also be employed in the purification of pyridoxine base and salts thereof containing undesired anions. Examples describe the conversion of pyridoxine hydrochloride, hydrobromide, sulphate and dihydrogen phosphate to pyridoxine base, pyridoxine hydrobromide to pyridoxine hydrochloride, and pyridoxine sulphate to pyridoxine hydrochloride.  Purification procedures are described from solutions containing free hydrobromic acid.
